"S.H.I.E.L.D. and their allies have never failed to keep Earth safe, but the sudden arrival of Mantis, Moondragon, and the artifact known as the Black Vortex, may finally tip the scales. The Black Vortex promises untold power to any who look into its depths. Cosmic power and clandestine antagonists promise a fierce fight between the forces of Earth and those from beyond." — Chapter Briefing
Important Notes:
The only way to recruit Mantis is to complete the list of Tasks.
One of the Tasks requires the defeat of an Epic Boss. This can be done by having the requirements needed to unlock the Epic Boss or by skipping the task by paying 30 Gold.
The requirements are:
"Moondragon has succumbed to its promise of Cosmic power! Star-Lord trusts S.H.I.E.L.D. only as far as he can throw the helicarrier, and decides to keep the Black Vortex safe and heal Moondragon without S.H.I.E.L.D.'s intervention. Well, most of S.H.I.E.L.D., the Agent is an honorary Guardian of the Galaxy after all." — Mission Preview
If Nebula is around, we need to worry about the Cull Obsidian showing up too. Maybe even Thanos. Get a hero over to the Helicarrier and make sure they know to be on the lookout. But don't mention the Black Vortex.
Send Star-Lord to touch base with S.H.I.E.L.D. Even if we can't spill the beans about the Black Vortex, we want them to know the Guardians are on the case.
"Theft! It looks like the remnants of the Hellfire Club heard about the Guardian's "secret cargo". How much help can S.H.I.E.L.D. provide while being kept in the dark? It might be time for Star-Lord to come clean before things go to hell in a handbasket." — Mission Preview
A combined contingent of Hellfire and Spartax personnel is holed up in here. Send a hero to root them out and make sure they're not...you know...hiding anything.
Rocket Raccoon is wiring up some kind of doodad that should help us track the Black Vortex. All he needs is someone to plant a signal booster on top of a skyscraper. Send a hero to get that done.
"The Black Vortex is too dangerous to keep lying around, seducing people with its cosmic power. There's only one problem, Cosmic Powered Spartoi and Villains, under the command of the ruthless J'son stand in the way." — Mission Preview
The emanations from the Black Vortex are drawing all kinds of attention. A HYDRA force is gathered here. They might be about to make a play for it. Take them out.
The Black Vortex might be inside this building, but we can't be sure without getting eyes on it. What we need is someone who can sneak in...maybe by shrinking...?
There's a group of A.I.M. scientists sniffing around the edge of our operational area. They might have detected some kind of signal from the Black Vortex. Send a hero to put them out of commission before they can contact MODOK and get him involved.
Rocket is racking up a serious Spartax body count, but we need him to add to it here. This group is covering the front of the building where we think the Black Vortex is being held.
